UNITED STATES SAMUEL FINE, OF PHILADELPHIA, PENNSYLVANIA.

HAND PLANE.

Application filed March 22, 1924. Serial No. 701,008.

To all whom it may concern:

Be it known that I, SAMUEL FINE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Hand Plane, of which the following is a specification.

This invention, generally stated, relates to a hand plane and has more especial relation to means for adjusting the cutting blade thereof.

The principal object of the present invention is to provide a single, efficient and comparatively inexpensive arrangement of parts whereby a rapid and accurate adjustment of cutting blade may be readily accomplished. A. further object resides in the provision of eccentrically arranged means for attaining parallel relation of parts between the cutting edge of a blade and the slot in the plane base and in the provision of other means operatively connected with respect to the eccentrically arranged means for adjusting said blade toward or away from the slot of the plane base. Other and further objects reside in the provision of general arrangement, combination and connection of parts for attaining the results sought by the foregoing objects.

The invention consists of the novel construction hereafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which Fig. 1, is a view in perspective of a hand plane embodying features of the invention, the cover plate being detached.

Fig. 2, is a view in central section of the plane including said cover plate,

Fig. 3, is a view in perspective illustrating a portion of the plane bed.

Fig. 4:, is a View in perspective of the plane cover plate, and

Fig. 5, is a view in plan of the cutting blade.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described Referring now to the drawings in detail, the numeral 1 designates the base plate of a hand plane of thetype made principally or wholly of metal. The base plate 1 is provided with the usual cross-slot 2. Fixed to and carried by the base plate 1 is a bed plate 8 which is arranged at an inclination to the base plate. This bed plate 3 is flanged as at 4., which flanges are downwardly extended. The numeral 5 designates an adjusting screw arranged in parallelism with the bed plate 3 and is journalled as at 6 in the rear flange of the bed plate and is also journalled as at 7 in a lug 8 projected from the under face of the bed plate 3. The bed plate is slotted u 3011 its upper face as at '9, see Fig. 3, and is urther milled out substantially V-shaped fashion as at 10 for a purpose to presently appear. The numeral 11 designates a cutter blade the cutting edge 12 of which is adapted to co-act with the cross-slot 2 of the base plate. The cutting blade 11 is apertured as at 13 to accommodate. an eccentricl l supported by an eccentric pin 15 mounted upon a carrier 16. This carrier has screw-threaded relation with, and is adapted to be operable endwise by means of the screw 5. Thus as the cutter blade 11 is moved toward or away from the cross-slot 2 of the base plate the carrier 16 moves a correspondin distance in the same direction. In order to provide lateral, adjusting movement for the cutting blade, use is made of eccentric 14. The latter is provided with an operating handle or lever 17 connected to the eccentric and accommodated within the V-shaped portion of the bed plate. By shifting the handle or lever 17 in the proper direction, the cutting edge of the blade 11 may be moved laterally to attain parallelism with the crossslot 2. This movement is possible because the blade is pivoted adjacent its cutting edge by means of set screw 18 which secures the cover plate 19 to the base plate and obvious ly maintains the cutting blade in abutting relation with the base plate. In order that the cover plate 19 may be readily applied and removed, an opening 20, in communication with a slot 21, is provided in said plate. By placing opening 20 over thumb-screw 18 and then shifting the cover toward the crossslot 2, the slot 21 is caused to cooperate with the stem of the thumb screw 18, so that when the thumb screw is tightened, the cover is clamped with respect to the bed plate. 'I he cutting blade is also provided with anopening 22 in communication with a slot 23 To position the cutting blade, the aperture'22 is first fitted over thumb-screw 18 and then the blade moved in a direction toward the cross slot 2 in the base plate so that the slot 23 engages with the stem of the thumb screw 18.

'The cover plate at its lower end abuts against the cutter blade and the upper pori I have in the present instance shown. anddescribed the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the splrit or scope of the invention or sacrificing anyof its advantages.

- "Having thus described my invention,

what I claim as new and desire to secure by Letters Patent, is:

A plane of the character stated comprising a base plate ,havinga cross slot therein, a bed plate having a lug upon its under side at the lowerend thereof and having a depending flange at its opposite end, the said bed plate having a'longitudinal slot arranged intermediate of said lug and flange, a longitudinally slotted cutting blade mounted upon said bed plate, an adjusting screw rotatably supported by said lug and flange, an eccentric carrier movable with said adjusting screw alongthe-slot in said bed plate, an eccentric operatively connected with said cutting blade and carrier,a cover plate ;ar-

ranged upon said cutting blade, and a set screw passing through said cover plate and the slot of the cutting blade for coacting with the lug of the bed plate to secure said cover plate in position andto form a pivot for the cutting blade, whereby in the movement of said adjusting screw the cutting blade may be moved toward said cross slot .and in the movementof said eccentric may be moved about 1ts pivot po nt.

In testimony whereof, I have hereunto SAMUEL FINE.

signed my name.
